FYI new extended feature launch tomorrow.  https://www.youtube.com/watch?v=WvTdNwyADZc&feature=youtu.be

I have been looking at the API and the ROS integration with Spot and I think a ARC plugin could be written fairly easily to provide some basic functionality.  Also SPOT has a sensor platform where you can add OEM sensors (Lidar, Robot Arms etc) so ARC would provide a lot of value.

So who has $75,000.

Adding a few more bearings and now also a second encoder per joint... I need to do a testing rig, but it is looking pretty good so far!

These guys managed to get very precise with their Cyclodials...

...now all we have to do is line up for a Markforge...heheheh (Onyx 1 is $4500 and the Onyx 2 is $10,000) Wonder how much a roll of carbon fiber filament costs?

Its a bit more expensive than ordinary filament and you need a hardened steel nozzle...there is no magic to it, any ordinary printer can print this! Its just a bit pricey for prototyping that's all!

How about another controller...this one called the Dizzy..controls BLDC motors like servos with 180 degrees.....

That is a VERY good find!!! The controller is only 35$ and it looks pretty amazing...with the encoder build in an hollow shaft being supported by design!! I am following the guy on YouTube but never realized, he is also selling products!!

Great...this could help to reduce the per joint cost! Quads are getting exponentially expensive...just way to much joints!!
